Also the edid blob ptr doesn't get updated during probe after suspend, because driver still uses the cached version( I checked that), which makes it impossible to check that the edid actually got changed because the pointer and blob is the same! To fix this need to call drm_edid_duplicate in drm_helper_hpd_irq_event before doing probing(drm_helper_probe_detect) which will modify connector->edid_blob_ptr and copy it to another blob then compare to the new one. Currently I'm implementing those fixes.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
